What is the Lewis Dot Structure of CH3COOH (Acetic Acid)? What is the difference between malic acid and maleic acid? ... What is the structure of malic and maleic acid?
Ball-and-stick molecular models are built and used for the consideration of hydrogen bonding possibilities in cis-1,2-dicarboxyethene (maleic acid) and trans-1,2-dicarboxyethene (fumaric acid). On the basis of the expected relative strengths of inter- and intramolecular hydrogen bond associations, students predict which of the two compounds has ...
Maleic acid is a colorless, crystalline organic compound used to make other chemicals and for dyeing and finishing naturally occurring fibers. It is combustible, although difficult to ignite, and is considered toxic causing extreme irritation to eyes, skin, and respiratory systems.
Maleic acid imides (maleimides) are derivatives of the reaction of maleic anhydride and ammonia or an amine derivative. This functional group is a popular constituent of many heterobifunctional crosslinking agents (Chapter 6).
Maleic and Fumaric Acids. Maleic acid is a much stronger acid than fumaric, even though they are simply the cis and trans isomers of butenedioic acid:
Each can be converted to the identical anhydride by heat treatment, but maleic acid reacts much more rapidly. This, coupled with the fact that mild hydrolysis of maleic anhydride (MAnh) leads to maleic acid, is linked to the cis structure of maleic acid and to the trans structure of fumaric acid (Scheme 1).
Maleic acid is an organic compound cmposed of 41.39% C, 3.47% H, and the rest oxygen. If .129 mol of maleic acid has a mass of 15.0 g, what are the empirical and molecular formula of maleic acid?
Best Answer: Maleic and fumaric acids are cis and trans isomers of each other. Look at the structure and you will see that maleic acid (even in its protenated form) can allow for hydrogen bonding by forming a seven membered ring type of configuration to allow the H on one of the COOH groups to hydrogen bond with one of the O's on the other COOH group.
reacting maleic anhydride with ethanol in the presence of catalytic quantities of sulphuric acid (Makowka et al 1989). As esterification process involves hazardous mineral acids, ecofriendly solid acid catalysts could be a convenient alternative. Hence, in the present study esterification of maleic
Maleic acid, also called cis-butenedioic acid (HO 2 CCH=CHCO 2 H), unsaturated organic dibasic acid, used in making polyesters for fibre-reinforced laminated moldings and paint vehicles, and in the manufacture of fumaric acid and many other chemical products.
The chemical properties of fumaric acid can be anticipated from its component functional groups. This weak acid forms a diester, it undergoes additions across the double bond, and it is an excellent dienophile. Fumaric acid does not combust in a bomb calorimeter under conditions where maleic acid deflagrates smoothly. For teaching experiments ...
A Lewis structure for Maleic acid (but-2-enedioic acid) is given below. It is an organic molecule that can be classified as both an alkene and a carboxylic acid(or more accurately adhesion in some polymers.
Maleic acid: Description: Maleic acid is an industrial raw material for the production of glyoxylic acid by ozonolysis. Maleic acid is an organic compound which is a dicarboxylic acid (molecule with two carboxyl groups). The molecule consists of an ethylene group flanked by two carboxylic acid groups.

DEFINITION AND STRUCTURE Maleic Acid is a cis unsaturated organic acid that conforms to the formula in Figure 1. Synonyms for Maleic Acid include 2-Butenedioic Acid, cis-1,2-Ethylene-dicarboxylic Acid (Gottshalck and McEwen 2004; Regist ry of Toxic Effects of Chemical Subst ances [RTECS] 2002), Malenic Acid, Maleinic Acid,
Fumaric acid is a chemical compound that occurs in plants like lichen and bolete mushrooms. It also forms within human skin when that skin is exposed to sunlight. In addition, scientists have created a synthetic version that is often used as an additive in several foods to enhance a sour flavor.

Maleic acid is quite different from Fumaric acid in a considerable number of ways. Here are some ways in which Maleic acid differs from Fumaric acid: Maleic acid is a less stable molecule than fumaric acid. The difference in heat of combustion is 22.7 kJ·mol−1. Maleic acid is more soluble in water, than fumaric acid.
Maleic acid or cis-butenedioic acid is an organic compound that is a dicarboxylic acid, a molecule with two carboxyl groups. Its chemical formula is HO 2 CCH=CHCO 2 H. Maleic acid is the cis-isomer of butenedioic acid, whereas fumaric acid is the trans-isomer.

Both are dicarboxylic acids. The structural formula of malic acid is HOOC-CH2-CH(OH)-COOH, and that of the other one is HOOC-CH=CH-COOH (cis-isomer of butenedioic acid).
Sigma-Aldrich offers a number of Maleic acid products. View information & documentation regarding Maleic acid, including CAS, MSDS & more.
However, fumaric acid's structure already dictates that it practically must form a network of coplanar molecules interacting with each other via hydrogen bond dimers from carboxylate to carboxylate. This is a very nice structure to keep. Maleic acid cannot form such an extensive network no matter how much it distorts.
